 Insulator (electricity)

An insulator, in the context of electricity, is a material that does not allow the easy flow of electric current. This is due to the high resistance of insulators in comparison to conductors (which allow electrical current to flow freely) and semiconductors (which have properties between conductors and insulators). Key characteristics of insulators include: 1. **High Resistance**: Insulators have very high electrical resistivity, meaning they resist the flow of electric charges.
